Encouraging sustainable insect-based diets: The role of disgust, social influence, and moral concern in insect consumption.

• Moral concern was found to be an additional influence on insect consumption. • Exposure to others consuming insects does not impact one's own willingness. • Exposure to others consuming insects reduces disgust and increases acceptability. • However, exposure only impacts beliefs under very specific circumstances. Disgust, social influence, and moral concern seem to play a pivotal role in insect consumption. Research examining these factors, particularly in the UK, is currently lacking. As a result, two studies were conducted to examine the perceived barriers and benefits of insect consumption, and how disgust can be counteracted. First, a cross-sectional study (N = 600) showed that disgust and moral concerns were unique predictors of individual's willingness to consume insect products. Second, we conducted an experiment (N = 519) to examine whether knowledge that someone else consumes an insect-based product impacts one's own willingness to consume insects. In this study we replicated Hartmann, Ruby, Schmidt, and Siegrist (2018) methodology of giving information about an insect consumer but added details about the individuals' occupation and what type of product they consumed, examining how these factors impacted individual's willingness to consume insect-based products. We found that this information did not impact willingness to consume; however, it did influence feelings of disgust and perceived acceptability. This study also replicated the first study by demonstrating that disgust and moral concern are barriers to insect consumption. We hope the current findings trigger future research to examine how disgust can be counteracted, and to better understand the role of moral concern in insect consumption. [ABSTRACT FROM AUTHOR]
